FIRE-EXTINGUISHER.

To all whom it may concern:

Be it known that I, WILLIAM'E. LUHMAN, a citizen of the United States, residing in Port Chester, in the county of Vvvestchester and State of New York, have invented certain new and useful Improvements in ,Fire- Extinguishers, of which the following is a specification.

vThis invention relates to an improved fire-extinguisher which is charged with water and discharged with a carbonate .solution and which` is provided with an acid-bottle the conten'tsof which' are supplied at thev time the extinguisher is required'for use.

In fire-extinguishers of' this class heretofore in use it 'was customary to break the bottle containing the sulfuric. or other acid by means ofpressure applied to the bottle. This required the replacing of the bottl after every use of the fire-extinguisher. This was annoying, inconvenient and ex ensive.

' The object of this invention is to ispense with the breaking of the glass bottle so that the apparatus can be charged'immediately after use without requiring a new bottle; and for this purpose the -invention consists in a fire-extinguisher embodying the ynovel features and combinations iof parts to be i hereinafter described and pointed out in the ,claims In the accompanying drawings, Figure 1 represents a side-elevation of my improved fire-extinguisher, Fig. 2 is a Vertical central 'section 'of the same, Fig. 3 is a' detail perspective view ofithe frame for supporting the acid-bottle detached from the extinguisher,

, Fig. 4 is a Vertical transverse section through the ,acid-Bottle. and its holder online 4, 4,

` porting t Fig. 2, and Figs. 5 and 6 :are perspective views respectively of the glass holder for 'the acid-bo'ttle and of the acid-bottle itself.

Similar letters of reference indicate .corresponding parts throughoutthe several figures.

Referring to the drawings, a represents a cylindrical receiver which is )referably made of copper or other suitable s eet-metal, and which is provided with' a tightly riveted bottom and with an opening in its to to which a cover b. provided with a hinged fiandle 61, is secured. On a recessed interior shoulder a1 on the upper part of the receiver a. i's supported the supporting-ring '1 of-a frame d for supie acid-bottle. The frame d is provlided with two downwardly-extending hangers d, of which the left-hand one is provided Speeification of Letters Patent.

with a disk 01'3 provided with a rim e14 in which the acid-bottlef and its inclosing shell']P1 are supported. At thelower part of the rim is a shoulder dx. The right-hand hanger has a cir'eular rim di' and a shoulder (Z6 at its 'lower part, the Shoulders (lx and d serving for supporting the inclosing shell1 which is split at 1ts lower part, as shown at fz, the edg'es of the 'split portion resting onV the edges 'of the Shoulders' (lx, d so as to prevent the turning of thesliell f1 when. the acid-bottle is 'turned on its. axis. The shell fl is preferablr 'of glass.v The acid-bottle is made of cylindrical shape and closed at the ends and provided with an opening fs through which it is filled with a suitable acid. l 'The right-hand end of the acid-bottleis provided with an obl'ong boss or projection f4 which is made integral therewith andr which is engaged lby the r'eis connected with an interior rotatable portionof a disk-shaped `valve o which is provided with a gudgeon in line ,with the ,studshaft that passes through, an inclosing casing v1. which abuts against stop-pins hl, hZ attached to the exterior head of the casing. The casple nx to which a'hose nhaving'a nozzle nl is applied.v The casing of the Valve vis attached to the upper part of ,the receiver-'uI and,

guisherthe receiver is opened"and the frame with the acid-bottle removed. The acidbottle is4 then removed from. its split shell,

filled vwith acid' and inserted, with the'dzischarge-o enin f51 at the upper part, into the glass she l f 1, tie letter fitting tightly around the acid-bottle and thereby closing it. When placing the holder for the, acid-bottle in posi- To the gudgeon is applied a handle hl cessedend of a key k, the s'tud-shaft ofwhich i ing is providedl at the upper end with a niption at 'the u per part of the receiver, 'the same is passe through the o ening until its upper part rests on the shoul er in the upper lart of the receiver. In this `position the ossf4 of the acid-bottle ases into the recessed end of the key k, w ichlatter is then inlvertical position. After the acid-bottle guisher into action the handle h is nioved through an angle of 180, until it is arrested by the lower stop-pin h, This turns the acid-bolttle on its 'axis to' a corres onding angle, so that its openin is locate on the surrounding shell at the Iower open part of the holder or shell and discharges freely the contents into the water in the receiver. By shaking the receiver the mixture takes place quickly and the gas generatedlcreates a sufficient pressure in the upper part of the receiver for forcing the water through the now opened-valve into thehose and through the hose and nozzle. w

When all the water is dis'charged the re ceiver is opened again by removing the cover, the holder for the acid-bottle removed and the latter charged With acid. The receiver is then recharged With a liquid saturated With a gas generated by carbonic or other acid, after which the acid-bottie is replaced in position and the cover tightly closed on the same, the holderbeing sup orted on the shoulder by its contact With t e cover b. Before the holder is dropped into position the Operating handle is returned into upper position against conta et with the upper sto -pin h* by which the recess of the ke k is p aoed in line With the boss of the acidottle, so that the same is placed 'in position in the recess, While the valve is moved into closedposition so as to prevent any escape of gas. vWhen the extinguisher is again required for use the same operation of opening the valve and discharging the contents of' the acid-bottle is repeated.

My improved fire-extinguisher has the following advantages: First, that the acid-bottle, notv being broken as heretofore, can be used again after each use of the extinguisher second, that the operation of the extinguisher is easily comprehendcd, consistmg merelv in the turning of the valve-lever from one position to the other and back again; and, third,

that` the recharging can be accompiished by any one With great facility.

Having thus described niy invention, I claim as new and desire to secure by Letters Patent: p

1`. In a fire-extinguisher, the combination of a receiver, an acid-bottle mounted therein 'to turn on its aXis and thereby discharge its lcontents, an Outlet-valve for the receiver,

means for Operating said valve, and a direct positive connectionbetween said bottle and said Outlet-valve whereby they are turned simultaneously.

2. In a fire-extinguisher, the combination of a receiver, an acid-bottle rotatably supported therein, a rotary Outlet-valve for the receiver, means for Operating said'valve, and a key connecting the valve with the acidbottle.

3. In a fire-extinguisher, the combination of a receiver, an acid-bottle rotatably and removably mounted ,therein 'and ,having a boss at one end, a rotary Outlet-valve for the receiver, means for Operating the same, and a -key extending from the body of said valve and engagingsaid boss.

4. In a fire-extinguisher, the combination of a bottle-supporting frame, a shell fixed in said frame and having a split lower portion, and a bottle mounted in said shell to turn t-herein andhaving an outlet to register with said split. portion.

5. The combination, with the receiver, of a frame supported therein,a shell fixed in said frame but freely removable therefrom, an acid-bottle mounted to turn in' said shell, and means operable from the exterior of the receiver for turning said bottle.

6. The combination, with the receiver, of'a frame mounted therein, circular rims carried at each end of said frame and provided with stops, a cylindrical shell supported in said rims and having a split portion fitting over said stops, an acid-bottle mounted to turn in said shell`and having an opening to register lwith said split portion, and means for turning said acid-bottle. 4

In testimony, that I claim the fore'going as my invent'ron, I have signed my name in presence 'of two subscribing witnesses.
